Title: Esophagus: Normal Lower Esophageal and Squamo-columnar Junction Mucosae


1
Esophagus Normal Lower Esophageal and
Squamo-columnar Junction Mucosae
2
Esophagus Normal Squamous Epithelium
3
Esophagus Normal Squamo-columnar Junction
4
Esophagitis (Inflammation and Reactive Epithelial
Changes of the Esophageal Mucosa) Has Many Causes
5
Reflux Esophagitis is the Culmination of
Gastro-Esophageal Reflux-Induced Changes in
Epithelial Cell Turnover
6
Esophagus G-E Reflux - Changes in Epithelium and
Vascular Papillae
7
Esophagus G-E Reflux - Defenses Against
Reflux-induced Injury
8
Esophagus G-E Reflux - Symptoms and Endoscopic
Findings in Reflux are NOT Predictive of Biopsy
Findings
9
Esophagus G-E Reflux - Heightened Epithelial
Turnover in G-E Reflux is Shown by Increased
Epithelial Tritiated Thymidine Labeling
10
Esophagus G-E Reflux - Reflux-induced Epithelial
Change Is a Consequence Of Increased Cell Turnover
11
Acute (Neutrophilic) Inflammation and Erosion In
Severe Reflux Esophagitis
12
Severe Epithelial Reactive Changes with
Eosinophils (EOS) in Gastroesophageal Reflux
13
Sequelae Of Prolonged G-E Reflux
14
Barretts Esophagus Development And Anatomic
Relationships
15
Endoscopic Landmarks In The GEJ Region Normal
Versus Barretts (Columnar-lined) Esophagus With
Location Of Lower Esophageal Sphincter (LES)
16
Requirements For Diagnosis Of Barretts Esophagus
17
Barretts Esophagus Gross Appearance
18
Barretts Esophagus Should Be Suspected And
Confirmed By Biopsy When The Squamo-columnar
Junction Is Displaced Or Highly Irregular
19
Barretts Mucosa (BM) With Submucosal Esophageal
Gland (SMEG) Below Muscularis Mucosae (MM)
20
Barretts Mucosa Distinctive (Specialized) Type
